Blac Chyna first sparked Rob Kardashian romance rumors in January, when she posted an intimate pic of herself in the arms of a man with tattoos identical to that of Rob's. Not surprisingly, the Internet lost its mind given Chyna's history with the Kardashian family. Chyna was previously engaged to rapper Tyga -- with whom she shares son King Cairo with -- and Tyga is now dating Rob's younger sister Kylie.

Rob and Chyna also didn't waste any time taking their relationship to the next level. The two got engaged in April, and one month later, they announced that they were expecting their first child together -- see point 15.

Kanye West is never one to hold back his opinions on Twitter, but the rapper topped himself in January when he went in on rapper Wiz Khalifa. West called the "See You Again" rapper's first single "corny as fu*k", claimed no one ever listened to any of Khalifa's albums "all the way through," but also gave him a backhanded compliment on his style.

"I think you dress cool, I wish I was skinny and tall," Kanye tweeted. "Maybe I couldn't be skinny and tall but I'll settle for being the greatest artist of all time as a consolation."

Of course, we can also thank the entertaining rant for giving us the best clap-back OF ALL TIME courtesy of Kanye’s ex, Amber Rose. Rose took offense when Kanye brought up her and Khalifa's son together, and referred to her as a stripper.

"Awww @kanyewest are u mad I'm not around to play in ur a*****e anymore? #FingersInTheBootyA**B**ch☝" she tweeted in response.

MIC. DROPPED.

3. Taylor Swift Slams Kanye During GRAMMY Album of the Year Speech

Something tells us Taylor Swift might regret this one. The singer -- who has a long history with Kanye -- not so subtly called him out for the lyrics to his song "Famous" during her acceptance speech for Album of Year at the GRAMMYs in February. The controversial lyric reads, "I feel like me and Taylor might still have sex / Why? I made that b***h famous."

Taylor slammed Kanye without actually naming him in her speech. "As the first woman to win Album of the Year twice, I want to say to all the young women out there, there are going to be people along the way who try to undercut your success or take credit for your accomplishments and your fame," she said. "But if you just focus on the work and you don't let those people sidetrack you, some day when you get where you're going, you'll look around and you will know that it was you and the people who love you who put you there and that will be the greatest feeling in the world."

Kim proved she wasn't afraid to take on her naysayers following the controversial selfie, when she went on a scathing rant against celebs who openly criticized her. Her targets included Bette Midler, Chloe Grace Moretz and Piers Morgan.

A sample of Kim's wrath? "Let's all welcome @ChloeGMoretz to twitter, since no one knows who she is," she tweeted about Moretz. "Your Nylon cover is cute boo."

SAVAGE.

Kim later addressed those who claimed she couldn't possibly be the author of her own comebacks. "Wait I can't believe people thought Kanye or Khloe hacked my Twitter," Kim hilariously tweeted. "I swear I'm funny too!!!"

These days, the couple's relationship appears stronger than ever, and has been able to withstand Rob and Chyna's relationship, as well as a little bit of financial drama on Tyga's part. Just last month, Kylie shared a super intimate pic of the two for the rapper's 27th birthday, calling him her "baby."

It appears it's really over between Khloe and her ex-husband, Lamar Odom. While Khloe memorably dropped everything to support Lamar after his health emergency last year -- and called off their divorce in order to continue making medical decisions on his behalf -- she refiled for divorce in May following reports that Lamar was still drinking alcohol.

Kim gave birth to her son Saint last December, and made her weight loss goals no secret. The mother of two impressively achieved those goals and more this year, losing an amazing 60 pounds after giving birth, which she credited to her Atkins diet. Of course, she had no problem showing off the results.

10. Kim Exposes Taylor's 'Famous' Conversation With Kanye

In what's now known as the day of the receipts, Kim took to Snapchat in July to share bombshell footage of Kanye allegedly getting Taylor Swift's blessing on the infamous "Famous" lyrics she slammed him for in February. While the clips she posted don't appear to be the full, unedited conversation, it sounds like that the "Blank Space" singer did indeed approve of her shout-out in the song.

Taylor denied that she ever granted her permission, noting "you cannot 'approve' a song you haven't heard" in her own statement. "Being falsely painted as a liar when I was never given the full story or played any part of the song is character assassination," she added.

Still, the backlash was swift, with some fans spamming her social media accounts with snake emojis.

Khloe embarked on a new relationship with NBA star Tristan Thompson this year, and it appears to be getting serious. The two were first linked when they were spotted on a trip to Mexico over Labor Day weekend, and in September, a source close to Khloe told ET that she and the Cleveland Cavaliers star were "full-on dating." Khloe even spent Thanksgiving with Tristan in Cleveland this year, skipping out on the Kardashian Thanksgiving at Kylie's house.

.... And her mother approves! Kris Jenner told ET in September Tristan was a "wonderful guy" when we asked her about Khloe's new beau.

13. Kim Robbed at Gunpoint in Paris, France

Kim has been on a social media break since her frightening robbery in Paris, France on Oct. 3. The reality superstar was held at gunpoint and robbed inside the luxury apartment she was staying at during Paris Fashion Week. A source close to Kim told ET in October that the reality superstar was "absolutely traumatized" by the incident.

Kanye was eventually released from the hospital on Nov. 30 after spending nine days at UCLA Medical Center, revealing a new blonde 'do. Earlier this month, a source told ET that "people in Kanye's inner circle are hoping the hospital stay has made him realize that he needs to take a step back from work and focus on his personal health and mindset."

17. Scott Disick and Kourtney Kardashian Get Close

Kourtney and her ex, Scott Disick, have remained pretty close this year and have even gotten a little flirty -- leading to reports earlier this month that the two are back together. However, a source close to the former couple told ET that the two aren't actually dating again.

But Scott "has been consistently on his best behavior for the past two months" to the delight of Kourtney," the source said. "He's not been partying or drinking. This is the first time we’ve seen Scott be this good in a very long time. Yes, that is always something Kourtney wanted for Scott -- to calm down and be at home."
